1 Oracle Spatial Summit 2015 Best Practices for Developing Geospatial Apps for the Cloud Nick Salem, Distinguished Engineer Neustar

2 Neustar ElementOne OVERVIEW Comprehensive cloud based GIS analytics platform Feature rich, secure and highly scalable application Provide rich data and cutting edge analytics to help clients acquire, retain and grow high value customers CHALLENGES / OPPORTUNITIES Need for 200% performance improvement on spatial queries, scalability, security for mission critical data Faster processing time for core spatial operations Faster query response time for large customer and transaction level datasets SOLUTIONS Oracle Database 12c Enterprise Edition Spatial Option with GeoRaster, Network Data Model Real Application Clusters Partitioning Advanced Security Option Oracle Fusion Middleware MapViewer RESULTS Consolidation of raster, vector, network data in 3 TB sized central repository Achieved up to 300x performance improvement for aggregating spatial geometries Up to 20x performance gains by organizing spatial data by proximity Up to 50% space savings by managing ordinate precision for coordinate transformation 10x performance gains in processing coordinate transformations Up to 8x performance improvement for spatial touch interaction queries 4x performance gains in spatial dataset join operations

3 The Spatial and Graph SIG The SIG promotes interaction and communication that can drive the market for spatial technology and data Members connect and exchange knowledge via online communities and at annual conferences and events Meet us at the Summit Morning Receptions Tuesday and Wednesday / 7:45 to 8:30 a.m. / Registration Area Birds of a Feather Session Tuesday / 12 to 1 p.m. / Lunch Room Join us online LinkedIn (search for LinkedIn Oracle Spatial ) Google+ (search for Google+ Oracle Spatial ) IOUG SIG (sign up for free membership through OTN Spatial Communities (search for Oracle Spatial and Graph Community ) Contact the Board at oraclespatialsig@gmail.com

5 Agenda Neustar Quick Intro Geospatial Analytics in the Cloud - ElementOne Order by Spatial Proximity Switching between Multiple Projections Miscellaneous Best Practice Tips 12c Spatial Vector Acceleration Benchmarks Live Demo

6 About Neustar NYSE: NSR $964 Million in Revenue Employees 14,000+ Customers 20 Billion Requests Per Day Marketing Services IT/Security Services Data Services SITE & MARKET ANALYSIS CUSTOMER & PROSPECT ANALYSIS MEDIA PLANNING TARGETING CUSTOMER INTERACTION MANAGEMENT

7 Neustar s ElementOne Platform Highly flexible and high performance mapping Rich market and trade area capability Road network / drive time analysis Heat themes GeoRaster images Aerials / terrain map overlays Centralized secure data repository

8 Order by Spatial Proximity Rows are stored in Oracle blocks Blocks are stored on disk and in memory Clustering Factor Order of data compared to index Use md.hhencode_by_level function to return a order by value See S&G blog for more details: _of_organizing_spatial Achieved 20x better performance using a 16M business table Compression, pctfree & sdo_rtr_pctfree

9 Switching between Multiple Projections On the fly dynamic transformation vs process once and store (see S&G blog*) Join user_segments & user_lobs to see space consumption of sdo_ordinates Layer (SRID) M Bytes ZIP Codes (8307) 120 ZIP Codes (3785) no rounding 216 ZIP Codes (3785) round ZIP Codes (3785) round *S&G blog:

10 Miscellaneous Best Practice Tips Geometry simplification Minimum vertices needed Topology and geometry relationships Build topologically smart processes Partitioning Query pruning Efficient data management 12c Point-in-Polygon function Does not need spatial index Use on global temp + external tables Parallel enabled

11 12c Spatial Vector Acceleration 300x faster SDO_AGGR_UNION 8x faster SDO_TOUCH 6x faster SDO_WITHIN_DISTANCE 6.5x faster SDO_JOIN 10x faster SDO_CS.TRANSFORM 3x faster SDO_GEOM.RELATE 2.6x faster SDO_GEOM.DISTANCE
